Varicose Vein Ulcer What The Hell Is This Thing On My Leg?

What the hell is this thing on my leg? - varicose vein ulcer

I have this somewhat unwieldy cm tumor in my right leg about 6 above the ankle. It seems that there is a ruptured vein through the skin. It does not hurt, but it looks and feels very strange. I have not heard that an ulcer, "his veins," but surely. Once dried, whatever, I scratched the itch is caused by a crust of blood and shot them like a madman. It was dark, it has not yet come to see if it pumps as you can imagine that your heart is pumping blood, but he made a deep blood stains on the bed, a foot long and one inch wide. I still think we bleed to death. Kind of freaks me out. No idea what it is, and if I in danger?
